For applications requiring less than 20 W of output power, the VIPer Plus series of integrated high voltage converter ICs are an excellent option. Typical applications include: power adapters, metering, auxiliary power for larger power supplies, and home automation. There are four different families of VIPer Plus noted by the final number in the part number. The VIPer 5 series is a quasi-resonant controller, all others are fixed-frequency with jitter. The VIPer 6 series is designed for non-isolated topologies and can be used to implement buck and buck-boost topologies as well as flyback. The VIPer 7 series is ideal for standard isolated flyback converters, and the VIPer 8 series is similar to VIPer 7, but with the added feature of an Extra Power Timer to allow for short bursts of up to 2x the steady state output power capability of the part.
